The LED light is an electroluminescent semiconductor material chip, which is solidified on the bracket with silver or white glue, and then the chip and the circuit board are connected with silver or gold wire, sealed around with epoxy resin to protect the internal core wire, and finally the shell is installed, so the LED light has a good seismic performance.

Because LED can directly emit red, yellow, blue, green, green, orange, purple and white light, they were used as the indicating light source for instruments and meters at the beginning. Later, led light colors were widely used in traffic lights and large-area display screens, resulting in good economic and social benefits. Take a 12-inch red traffic light, for example. In the United States, the long-life, low-light, low-efficiency 140-watt incandescent lamp was originally used as the light source, which produced 2,000 lumens of white light. With the red filter, 90% of the light is lost, leaving only 200 lumens of red light. For the new lamp, Lumileds USES 18 red LED lights that use a total of 14 watts, including circuit losses, to achieve the same luminous effect.The automobile signal light is also the LED light source application important domain.

LED lights have the characteristics of high efficiency, environmental protection and long life.
